The cast of The Big Bang Theory had a hard time accepting Jim Parsons' exit from the show. Johnny Galecki admitted that he wasn't happy with how it happened, as Parsons didn't give any warning beforehand. However, the final season went smoothly, and the emotional finale brought closure. What Parsons didn't expect was a show centered around his character, Sheldon, during his younger years.

The success of Young Sheldon, with six seasons and 113 episodes, surprised Parsons. He was particularly moved by Iain Armitage's portrayal of young Sheldon. Parsons told EW that watching Armitage bring the character to life was a profound experience.

Parsons also credited Young Sheldon for reminding him of how much he loves his job. Seeing Armitage's dedication and talent reinvigorated his passion for acting. However, Parsons initially had reservations about the idea of a Big Bang Theory reboot. He was not a fan of spin-offs but was assured that Young Sheldon was its own unique show, an origin story.

The show's success has proven Parsons wrong, and he now believes that Young Sheldon can be enjoyed even without prior knowledge of The Big Bang Theory. Parsons was impressed by Armitage's audition, as he was the first to make the creators laugh. Armitage's talent and dedication won him the role, and it has been a transformative experience for him. Jim Parsons takes pride in Armitage's success on the show and continues to support him.
